Device and method for drying and deagglomerating

Abstract

The invention relates to a device and method for drying and deagglomerating moist feed material, whereby the feed material is kneaded, mixed and broken up by the action of at least one roller rolling on a driven plate and is dried by means of hot gas supplied thereto. The invention also relates to a method for converting this device into a mill drying device, whereby the at least one roll is provided with a pressing device.

1. A method of drying and deagglomerating moist feed material, characterised in that at least 70% of the feed material has a particle size of less than 200 μm and the feed material has a moisture content of 15% to 50%, the feed material is kneaded, mixed and broken up by the action of at least one roller ( 2 ) rolling on a driven plate ( 1 ) and is dried by means of supplied hot gas and wherein the material bed forming on the plate is detached and broken up. 
     
     
       2. A method according to  claim 1 , characterised in that some of the feed material which has already been dried is fed back to the grinding plate.
